The state framework sets the default. Where Versant Power pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Maine has two NEB variants: a kWh Credit Program that credits participating bills in kilowatt-hours, and a Tariff Rate Program for non-residential customers that provides dollar bill credits based on the PUC-set tariff rate and facility output. |
|---|---|
| Export rate | There is no single statewide export price. The kWh Credit Program provides kWh credits rather than a fixed dollar rate; the Tariff Rate Program uses annually established, project- and customer-specific tariff rates published by the PUC. |
| Rate effective | Tariff rates are established for 12-month periods beginning January 1 and ending December 31; the PUC page states its current rate schedule was established on December 17, 2025 for periods through 2046. |
| Credit rollover | Yes. Unused kWh or dollar credits may be accumulated and applied on a rolling 12-month basis. |
| Credit expiration | Unused kWh or dollar credits are eliminated at the end of the applicable 12-month period, with no compensation for the unused credits. |
| Annual true-up | No separate annual true-up date is specified in the reviewed sources; credits are handled on a rolling 12-month basis and expire at the end of that period. |
| Aggregate program cap | No statewide aggregate percentage cap is stated in the cited statutes or MPUC NEB page. Section 3209-A states a 750 MW development goal; that is a goal, not described as an aggregate program cap. |
| Program status | The 2025 law bars the Commission after December 31, 2025 from allowing new NEB agreements for resources interconnected or planned on the utility side of a customer meter; existing agreements and behind-the-meter arrangements are governed by the applicable statutes and rules. |
| Grandfathering | Yes, in limited statutory/program respects: the commercial and institutional collocation/100%-subscription limitation does not apply to a NEB agreement executed on or before December 31, 2023, and statutory applicability provisions preserve the significance of earlier agreements and milestones. |
| Regulator | Maine Public Utilities Commission (MPUC). The CMP and Versant tariff agreements identify the Commission as the state regulatory agency with jurisdiction over public utilities. |
| Governing rule | 35-A M.R.S. §§ 3209-A and 3209-B, implemented through the Maine Public Utilities Commission Chapter 313 Net Energy Billing rule. |
| Pending change | No separate pending change was identified in the reviewed sources as of September 16, 2026. The material 2025 changes are enacted law: after December 31, 2025, new utility-side-of-meter NEB agreements are barred under §§ 3209-A(10)-(11) and 3209-B(9). |
